飞机在结冰气象条件下容易发生结冰现象，冰的存在会破坏飞机气动特性，影响飞行安全，严重结冰可导致机毁人亡，故必须及时将冰移除。电热除冰是目前最常考虑的除冰方式之一，本文系统介绍了电热除冰装置及其工作原理。首先，主要围绕除冰过程的传热特性、冰层力学特性和冰脊的形成，详细阐述了国内外电热除冰研究的发展。然后，针对国内外研究存在的一些问题，提出了几点对电热除冰研究的粗略想法，电热除冰数值计算方法和模拟技术研究、热力耦合特性对冰层融化和力学特性的影响研究、冰脱落准则和运动规律研究是未来研究需要重视的方向。

Aircraft might experience icing when passing through icing clouds containing supercooled water droplets. Ice accretion is one of primary hazards to the flight safety, which would deteriorate aircraft aerodynamics characteristics to affect the flight safety. It is important to remove ice on the aircraft. Electrothermal de-icing is one of the most widely applied techniques for aircraft de-icing. This paper discusses the method and the working principle of electrothermal de-icing equipment. Firstly, the studies of electrothermal de-icing are reviewed, including those related with heat transfer and mechaniccal characteristics and ice ridge formation during aircraft electrothermal de-icing process. Secondly, some practical issues about electrothermal de-icing are discussed, including numerical simulations, electrothermal de-icing techniques, effects of coupled thermo-mechanical characteristics on melting and mechanical characteristics, ice shedding and movement.
